ARMORED INTERLINER.

Application led July 12,

T @ZZ whom t may concern.'

Be it lrnown that I, ALBERT MANvERs, a subject of the King of Great Brit-ain, and resident of London, England, have invented new and useful Improvements in Armored lnterliners, of which the lfollowing is a specication.

This invention of improvements in armored interliners for use in connection with pneumatic tires has relation to puncture proof shields of the kind comprising a plu-l rality of overlapping metal plates mounted on a band or carrier and placed between the air tube and the casing.

The invention has for its object to provide improvements in such puncture pro-0f shields. to prevent creeping thereof in relation to the casing and air tube, and generJ ally to improve their construction.

According to this invention, a puncture proof shield comprises a plurality of metal plates, each curved in two directions, and hr :ing yone or more projections on the side that comes next the casing, a band or car rier of elastic material of a width greater than that of the plates, and flexible hinges to connect the plates to the band or carrier, said plates furthermore being depressed or offset on one side to receive the overlapping edge of the adjacent plate.

ln order that the invention, the nature and lobjects of which have been set forth, may be clearly and readily understood, reference will now be made to the accompanying i drawings, on which- Fig. l is a perspective view illustrating the application of the puncture proof shield to a pneumatic tire;

Fig. 2 is a. plan view of the puncture proof shield; and

Fig. 3 is a side elevational view, part being in section.

The band or carrier l is made of a length of elastic material, such as elastic webbing, which is extensible in one direction only, and is of a width greater than that of the plates 2. The ends of the band or carrier l are united to constitute a member, the circumferential length of which is such that when placed in position on the air tube 3, and the latter is inflated, it is stretched and tends to bind or grip the air tube. The metal plates 2 are curved in two directions to correspond with those of the inner face 1923. Serial N0. 651,003.

'of the casing. Each plate 2 is hingedly connected with the band or carrier l, the hinge being constituted by a thin piece of leather l attached as by eyelets to the underside of a plate 9. and also to the band or carrier 1 as by sewing. Each plate is also depressed or offset along one edge as indicated at 5, the hinge t being connected to the depressed or offset side, and the offset such that the overlapping plates present lor have a substantially smooth and continuous upper surface. Each of the plates 2 has one or morel proj ections 6 from its upper face which, when the shield is in positio-n, engage the casing. Also, each plate is formed with a corrugation 7 arranged transversely of the plane of the wheel.

The shield is placed between the air tube and the casing, and when the air tube is uninflated the loverlapping edge of one plate lies closely against the shoulder of the offset portion 5. When the air tube is in- Hated, the plates are caused to move relatively to one another so that a small space is formed between the overlapping edge of one plate and the shoulder of the offset portion 5.

That l claim isz- A puncture proof shield for use with tires of the type referred to, comprising a plurality of metal plates each curved in two directions and having projections on the side that comes next the casing consisting of`trans verse ribs and studs spaced therefrom for engagement with the casing, a carrier of elastic material embodying a length of elastic material of a width greater than that of the plates and eXtensible only in the direction of its length, flexible material hinges connecting the plates to said elastic carrier l and forming relatively fixed bases therefor, said hinges riveted to the plates and attached by stitching to the carrier with each plate overlapping the plate adjacent thereto, and the said plates depressed at one side to receive the overlapping edges of the adjacent plates and to provide spaces between the shoulders formed by the depressed sides and the edges of the overlapping plates in normal position thereof.
